Measurement or calibration problems
Please include the device type, browser name and version, operating system, approximate display size, selected unit, browser zoom level and calibration method. If you use more than one monitor, tell us which display was active.
Page or translation corrections
Include the page address, language and the sentence or control that needs attention. Specific examples are easier to check than a general report and help us correct one area without changing unrelated content.
Accessibility feedback
If a control is difficult to reach by keyboard, touch, zoom or assistive technology, describe what you expected to happen and what happened instead.
Privacy requests
For privacy questions, state the subject of your request without sending unnecessary sensitive information. Do not send passwords, payment-card numbers, government identification numbers or security codes.
